in this study various two-stage processes were investigated for biological hydrogen production from olive mill wastewater (OMW) by Rhodobacter sphaeroides O.U.001. Two-stage processes consist of physicochemical pretreatment of OMW followed by photofermentation for hydrogen production. Explored pretreatment methods were chemical oxidation with ozone and Fenton's reagent, photodegradation by UV radiation, and adsorption with clay or zeolite. Among these different two-stage processes, strong chemical oxidants like ozone and Fenton's reagent have the highest color removal (90%). However, their effluents were observed to be unsuitable for both hydrogen production and bacterial growth. On the other hand, clay treatment method was selected as the optimum process that allows fast and low-cost treatment as well as its effluent found to have the highest hydrogen production potential (31.5 m(3) m(-3)). Spent-clay regeneration was also investigated on the grounds that solid waste minimization is important for the overall efficiency of this process.

Effect of iron and molybdenum addition on photofermentative hydrogen production from olive mill wastewater
Eroglu, Ela; Gündüz, Ufuk; Yucel, Meral; Eroglu, Inci (2011-05-01)
Photofermentative hydrogen production from olive mill wastewater (OMW) by Rhodobacter sphaeroides O.U.001 was assessed under iron and molybdenum supplementation. Control cultures were only grown with 2% OMW containing media. The analysis included measurements of biomass accumulation, hydrogen production, pH variations of the medium, and changes in the chemical oxygen demand (COD) of the wastewater. Growth under control and Mo-supplemented experiments yielded about the same amount of biomass (similar to 0.4 ...
Removal of imidacloprid from wastewaters by ozonation and photo-ozonation
Sönmez, Büşra; Dilek, Filiz Bengü; Department of Environmental Engineering (2019)
The widespread occurrence of micropollutants in the receiving water bodies apparently shows that conventional wastewater treatment plants (WWTP) are not capable to remove these compounds. Imidacloprid (IMI), which is a specific pollutant and an insecticide, exceeded Environmental Quality Standards (EQS) value (0.14 µg/L, annual average) in several receiving water bodies of WWTPs in Yeşilırmak basin. With the aim of examining advanced treatment methods to meet EQS value and to achieve good surface water qual...
TREATMENT OF EFFLUENTS FROM HEMP-BASED PULP AND PAPER-INDUSTRY .1. WASTE CHARACTERIZATION AND PHYSICOCHEMICAL TREATABILITY
Dilek, Filiz Bengü (1994-01-01)
This study was conducted to determine the wastewater characteristics as well as the treatment alternatives for the Tafkopru Pulp and Paper Mill in Turkey. The physico-chemical treatability study was conducted by standard Jar-test equipment. The highest COD removal efficiency obtained was 96% for the paper machine, 50% for the alkali extraction and 20% for the bleaching effluents by using alum as coagulant. The colour removal efficiency was around 80% for the alkali extraction effluents.
Effect of clay pretreatment on photofermentative hydrogen production from olive mill wastewater
Eroglu, Ela; Eroglu, Inci; Gündüz, Ufuk; Yuecel, Meral (2008-10-01)
The aim of this paper was to gain further insight into the effect of the clay pretreatment process oil photofermentative hydrogen production. This two-stage process involved a clay pretreatment step followed by photofermentation. which was performed under anaerobic conditions with the illumination by Tungsten lamps. Rhodobacter sphaeroUts O.U.001 was used for photofermentation. Higher amounts of color (65%), total phenol (81%) and chemical oxygen demand (3%) removal efficiencies were achieved after clay pre...
